I added an MSCOMM control to form in form designer.
I need that this control will not be created this control in not present on the user's computer.

Is it sufficient to add

RETURN .F.

to init event of activex control in form to prevent error if this control is not present in user's computer ?

I cannot test it in my computer since it is not possible to unregister mscomm control.
regrvr32 /u shows success but if I run the form, the control is registered automatically. Why?
